T (Lilli/7mm it may concern/.-

Be it known that I, FRANK R-.- WE'Ls a citizen of the United States; residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Loose-Leaf Binders, of whielrthefollowing is a specification.

My invention has relation to a binder whereinloose leaves may be readilyin'scrted and removed and when inserted may be locked or r for the leaves;

. top or removable section disunited from the back'and'other section of'thebinder. Fig. 3 'is a transyer'se sectional view on the line .a: Ca

held: against accidental and intentional reg noval', and in suchconnection it relates more particularly to the construction and arrangement of such a binder.

"The principal object-'of my invention is to providea binder for loose leaves comprising two separable sections whereof one has a solid back and the other is adapted to be locked-to said back, the solid back being provided with an extensible leaif-helder and the removable section being provided with. locking-prongs My inventiomstated 1 general terms consists of a loose-leaf binder constrncted'and arranged in substantially the manner hereinafter described and claimed.

The nature and scope of my inventionwill bemorc fully understood from the following description, taken in connection with the ac-' companying drawings, formingpa'rt hereof, in which- Figure 1 is top or plan view of a loose. leaf binder embodying the main features of my invention, a portion of the top or removable section being broken away. Fig. 2 is an end elevational view of the binder with the -5 is a-n'enlarged cross-sectional view on and Fig. Visa-plan the line y y of Fig. 3. Fig.6 is an enlarged perspective-view of the prong and locking-v plate'of thei einfovable section of the-binder, viewof thetinner end of a removableleaf.

Referringto the drawings, ais the lower, and b the nppr or removable, section or cover of the binder. The lower section or cover a is permanently hinged or flexibly secured to asolid back d. 7 In' the backd is secured a lock e, an example of the construction of which is shown in Fig. 4, and the essential feature. of which consists of the two beveled springcatches e'e', projecting beyond the lock-case e" and adapted to'entera slot 11' in a locking-plate 5 secured to the cover I) to lock saidcovcr to the back d. One. oi the spring-catches e is" carried bya bar e, normally held in locked position by the spring 6 This bar a has a projection or arm e, toggled by means of a lever e to a secondbar e, which carries-the se'cond catch e. The arrangement and connection of the bars e and e is such that the spring e serves normallyv to push both rods and their catches e inward toward each other. The lock mechanism e is so arranged as tepnsh both rods (2 and eontward against the tension of the spring e A key insert'c in a keyhole located at the rear face of the back serves to expand the catches e e to enable the cover I; to .be disengaged from the same. v

-' To 'the back dis united the expansible leafholder, which comprises a plate fl-securely united to the back near where the lower or fixed cover is hinged. The plate f has two tubular projections or sockets f" f ,in which are adapted to slide the headed pins f f projecting downward from the second plate f which, with the plate f, constitutes the leafholder; Aspring f, inserted below the lower headed end of each pin f serves normally to elevatethe pins f? and to retract the plate f away from the plate f. The upper plate f has also one or more pins fientcring theback dto more effectually guide said plate toward or away'from the lower plate f of the holder.

Each plate fand f is'also perforated, as at f, 'to receive the locking-prongs b each of which depends from-a locking-plate 7. of the movable section or cover I);

A form of leaf designed to be. with the binder is illustrated in detail at Fig. 7. The

leaf comprises, essentially, a body;h,l iexibly united to a binding edge 71 by. a'fstrip h, of muslin or othertextile fabric... '-l?hebinding.

edge h of the leaf has two sets ofjperfore tions m and moi which sets m areclcsig'ned' to receive the loeki'ng prongs Z) of the cover and are cut whdllywithin the confines oi the e ge whereas'whe. other set have doloo f or soekei'sj" into the perforations w.

Having thus described the nature and objeets of myinvention,what I claim as new, and desire to secure by Letters Patent, -is

.In a loose-leaf holder, aisolid back towhich 10 one of the covers is floxiblyunited, anexpansible leaf-holder seeh'red to said back, and

comprising two plates whereof one is pro vided with tubular sockets and the other with pins nthtptod to slide in said soehets, springs adapted normally to elevate the pins in said sockets, and a detachable cover adapted to be locked to said back and provided with lookingprongs adapted to traverse one of the plates of the leaf-holder, substantially as and for the purposes described. r

In testimony whereof I have hereunto set my signature in the presence of two subserio- I ing witnesses.
